Don't worry, I'm sure your future kids won't mind much about their parents telling them their experience with dating, dancing, and things about prom night. Your future kids might even be too embarrassed to want to talk about it, just like most kids are. You should just do your best to comfort them, like telling them not to worry. After all, it's just a dance night. People take it so seriously, though. I mean, even if someone doesn't have a date, its not the end of the world, is it? It's a pretty fun night to just hang out in prom night, too. Especially if you got some friends that also don't have dates. If you do have a date, it's also really awesome. So, basically, I would tell them that they should just relax and enjoy it, after all, how many times does prom night happen?
